changes = downtime. Has been since the advent of computing
Not if you have a competent devops team and a deployment pipeline.
I'm sure they have both but complex shit breaks when you change it often.
Has GitHub been down more since its acquisition by Microsoft?

How many req/s before you fell over?
I often wonder what kind of stack websites that fall over under HN traffic have. From my perspective HN doesn't actually bring that much traffic, so I find it curious which software is so fragile to fall over when getting HN front page traffic.
Before you have that need it seems like premature optimization. If I had a blog that was getting a handful of views/day, I probably wouldn't bother with CDN/scalability until it became an issue. Or use something like Medium (which I do).

#134tl;dr yes - and an exception to Betteridge's law!!! https://en.wikipedia.org/wiki/Betteridge%27s_law_of_headline...
tl;dr maybe - is that an exception?

#135This was prompted by the latest "Github is down" (now transformed to "Github was down" by the arrow of time):

Yeah, I've always thought blogs that didn't render to static pages were just sorta silly - for just a few hits a day, it's very simple, and if you get a flood of traffic, even a small vps could keep up.

But why even start with an assumption that is so likely to be wrong? We know that incidents are frequently correlated. We know that scale and complexity add fragility. We know that GitHub has gotten bigger and more complex. The chance of the probability distribution holding constant over 5 years of major growth is basically zero.
We are talking about different things. One is about attributing causes to an increase in failure rate, the other is about verifying whether there is any material increase in the rate at all. My comment addresses the latter as a back of the envelope calculation. Strictly speaking, when looked at through a fine toothed comb, yes the assumptions are very likely wrong. All models are wrong [0], but some of them are usefu…
I see where you're coming from and I agree with you overall, in particular how this is a first cut approximation.
But I still want to nitpick the details a bit. If you want to determine whether there was a change in the failure rate, you need to use rate statistics - failures per service-hour. Your analysis is only using the numerator while we know the denominator (the number of services in GitHub that can go out) has increased over time - GitHub Actions and Packages are relatively new.

I, for one, enjoyed your little foray into the field of statistics. So much so, that I'd love to learn some of this stuff as well! I'm a bioinformatics student, so I have a rigorous math background (analysis, linear algebra), but for some reason, our course is quite light on statistics and probability.
What resource would you recommend to get an intuitive grasp of statistics?
To give you an idea about what kind of resource (book) I'm looking for: I'm currently reading Elements of Statistical Learning and I enjoy that it has all the mathematical rigour I need to really understand why all of it works, but also that it's heavy on commentary and pictures, which helps me to understand the math quicker. Counterexamples: Baby Rudin one one side of the spectrum, The Hundred-Page Machine Learning Book on the other.

A few years from now it will be the brand of the most widely used Linux distribution.
Do we know it’s not there already? Can’t quickly find any installs count.
Both wsl1 and 2 are optional installs. So the number is not that big. Curl.exe on the other hand is installed by default.

#140They are porting things over to ASP.NET on Azure.
If the implication is that asp.net or Azure are unreliable then think again
